6 Claims.

This invention relates to shoe supports and more particularly to meansfor supporting the heel end of alast during an operation on a shoecarried thereby. The invention is illustrated herein as embodied in amachine of. the type de scribed in Letters Patent of the United States,No. 1,549,243, granted Augustll, 1925,'on an application of E. E.Winkley, having a sole-pressing member or pad arranged to apply pressureto the bottom of a shoe on a last and a jack for supporting the shoeagainst the pressure of the pad. It is to be understood, however, thatthe invention is not limited to shoe supports for use in machines ofthat particular character.

An object of the invention is to provide a jack having an improved heelsupport provided with means for spreading those portions of the upper ofa high shoe projecting above the top of the last to prevent pinching ofthe upper between the top of the last and the heel support. To this endand in accordance with a feature of the invention, the heel support isprovided with a rocker engageable with the top of the heel end of thelast and movable by its engagement with the last prior to thepressure-applying operation to operate a pair of arms which are swungoutwardly to spread the upper and lining away from the top of .the last,the arms being carried by the heel support and normally held adjacentthereto.

The above and other features of the invention, including various detailsof construction, willnow be more particularly described by reference tothe accompanying drawing and thereafter pointed out inthe claims.

' In the drawing,

Fig. 1 is a front elevation of the head of a machine of the type shownand described in the above-mentionedpatent, with the invention appliedthereto;

Fig. 2 is a vertical section support, and

Fig. 3 is a section on the line III-III of Fig. 2 illustrating theaction of the fingers on the upwardly projecting portion of a shoeupper.

The present invention is illustrated as embodied in a solepressingmachine of the type shown in the above-mentioned Winkley patent to whichreference can be had for a more de-. tailed description of theconstruction, arrangement and operation of parts not'fully describedherein. The machine is provided with a pair of upwardly extending rodsIt], only one of which is illustrated herein, which guide a pad box I2for vertical sliding movement. Carried by the pad through the heel boxI2 is a resilient sole-pressing pad I4 shaped to conform substantiallyto the curvature of the bottom of a shoe being operated upon. After ashoe has been placed on the pad. [4 the pad box is moved upwardly tocarry the shoe into engagement with a jack l 6. This jack comprises ahead I8 secured to the upper endsof the rods 10, and depending posts 20,22 adjustably secured tothe head and carrying respectively atoe-engaging roll 24 and a rocker 26 arranged to engage the heel end ofthe last.

. The rocker 26 is shown more clearly in Fig. 2 as mounted for tippingmovement at the bottom of the post 22 and for this purpose is providedwithan arcuate surface 28 received in a correspondingly shaped groove 30in the lower end of the post. A pin 32 in the lower end of the postpasses through an arcuate slot 34 in the rocker to guide the lattermember in its movement with respect to the post. normally held in theinclined position shown in Fig. 2 by a tension spring 36,. the upper end.of which is secured to a pin 38 in a slot 40 in the post 22 and thelower end of which is connected to the rocker by a link 42. As the shoeis carried upwardly by the pad box the left end of the rocker as viewedin Fig. 2 first engages the top'surface of the heel end of the last'andupon slight fur ther upward movement of the pad box, the rocker turns ina clockwise direction until the bottom surface thereof is in contactwith the top surface ofthe last.

This. movement of the rocker 26 prior to the sole-pressing operation isutilized to actuate means for spreading the lining and upper at the topof a high shoe or boot such as the shoe S shown in Figs. 1 and 3 so thatthe materials of The post is slotted in' the vicinity of the cars 48 asshown in Fi 3 to accommodate the arms 44. When the pad box 12 is initslowermost position the lower ends of the arms 44 .are in the dottedline positions shown in Fig. 3 and are thus held by a compression spring50 passing through the post 22 and engaging projections 52 carried bythe arms 44 above the pivots 4B. The lower ends of the arms are curvedtoward each other as shown in Fig. 3 so that at the beginning of theupward movement of the pad box the arms will enter the shoe and start tomove the lining The rocker is thereof. 'The ends of the pin are roundedas shown in Fig. 3 and cooperate with inclined surfaces 58 on the arms44 so that downward move-:

ment of the link 42 as the rocker moves relaend of a last, meansnormally maintaining said rocker in a position in which said surface isinclined to the post'but permitting movement of the rocker relatively tothe post as it engages a last, upper-engaging means carried by said postarranged to be moved outwardly thereof to spread the upwardly projectingportion of an upper away from the last, means normally maintaining saidupper-engaging means adjacent to said post, and means operated by saidrocker in response to its movement by engagement thereof tively to thepost 22 carries the pin 54 downwardly and exerts a cam action. on thearms 44 i forcing them outwardly into the positions shown in Fig. 3. Itwill thus be seen. that those mate rials of the shoe which extend abovethe heel end of the last are efiectively spread apart thus elim inatingany danger of the material beingcaughtbetween the lower end of the heelsupport and the operation thepad box 12 moves downwardly thus carryingthe last out of engagement with the rocker 28',lwhereupon the spring 36moves the rocker back into the position shown in Fig. 2, the pin 54'carried by the link 42 moving upwardly thu permitting the arms 44 tobe-moved inwardly by the spring 50 to their original positions;

Having described my invention, what I claim as new and desire to secureby Letters Patent of the United States is: a

1'; In a heel support for a last, the combination of a supporting post,a last-engaging member carried by said post for tipping movement andarranged tobe thus moved relatively to said post in response toengagement of the member with a last; upper-engaging means carried bysaid ost arranged to be moved outwardly thereof to spread the upwardlyprojecting portion of an upper outwardly of the last, means normallymaintaining said upper-engaging means adjacent to said post, and meansoperated by said last-engaging memher in response to its movement byengagement thereof with the last for moving said upper-enga ging meansoutwardly.

2. In a heel support for a last; the combination of a supporting post,alast-engaging member carried by said post for tipping movement andarranged to be thus moved relatively'to said post in response toengagement thereof with a last. a pair of arms pivoted to said post andarrangedto be moved outwardly thereof to spread the upwardly projectingportion of an upper away from the last, means normally maintaining saidarms adjacent to said post; and means operated by said last-engagingmember in response to its movement by engagement thereof with a mentrelatively thereto and having a surface ar'- ranged for engagement withthe top of the heel with a last for moving said upper-engaging meansoutwardly.
